The idea of Jupiter becoming a star comes from the book 2010:Odyssey 2 by Arthur C Clarke, where the Monoliths (Giant advanced devices seeded around the galaxy by an unknown race that wants to maximize the potential for intelligent life), increase the density of jupiter, by some large fraction, cuasing the internal pressures to become high enough toignite fusion. This has the effect of making Europa, Ganymede and Callisto of a suitable temperature for habitation, with Europa having native lifeforms (in it's ocean), and Ganymede and callisto being easyer than Mars to colonise. I think that terran_emperor's idea was that if in SCP, the local governmentcaused this to happen, I would give them an advantage in term of easy colony enhancement, or even terraforming. the only prolblem with this is that in the book, the change in Jupiter wasn accompanied by a very large explosion, which would have destroyed any colonies, if they were present.
